Shared mailbox with virtual domain

I’m trying to wrap my head around shared mailboxes served below a virtual email domain.
The kopano installation is serving domain1.tld. This works fine. The shared mailboxes are created to use domain2.tld.
domain2.tld is defined in postfix as virtual, with a ‘catch all’ to redirect unknown recipients to a sink:
# Virtual # Various entries for domain1.tld @domain1.tld email@example.com domain2.tld anything # firstname.lastname@example.org email@example.com # Tried, SOFTBOUNCE # firstname.lastname@example.org shared_mailbox # Tried, SOFTBOUNCE email@example.com firstname.lastname@example.org # Sink email@example.com firstname.lastname@example.org # Never executed @domain2.tld email@example.com
Postfix is configured to search on mail attribute to find users / mailboxes, shared_mailbox is defined in LDAP with mail attribute firstname.lastname@example.org.
Whatever I try, emails directed to email@example.com or firstname.lastname@example.org either end up in the sink or with a status=SOFTBOUNCE (User unknown in virtual alias table)
Aliases are searched for both virtual and LDAP, ldap attributes with virtual email-addresses on shared_mailbox make no difference in outcomes.
I’m bumping my head. Apparently, I’m missing something obvious. Any ideas what that might be?
